Between two soil series, Bajoa soil possessed the greater sorption (645.12 µg/g soil) with increasing the sulfur concentration. Beside this, the Gopalpur soil series showed sulfate sorption (550.76 µg/g soil) probably due to its higher pH (7.9); lower CEC (17 Cmol(+)kg-1), organic C (0.64%) and clay content (31%) than Bajoa (pH 6.9; CEC 22 Cmol(+)kg-1; Organic C 0.70; clay content 35%). On the other hand, at the presence of acetate anion, the amount of sulfate sorption in both soil series was decreased due to the competition between the sulfate and acetate anion on the exchange site. The Frundlich equation showed the best fit with higher value of coefficient followed by Langmuir and Temkin. The Langmuir equation has explained the Maximum Buffering Capacity (MBC) and the ...
